Vortex Space Warp 59
Periodic Variation group
These settings introduce variations into the force
by affecting the Basic Torque value randomly. You
can set two waveforms to produce a noise effect.
Enable—Turn on to enable the variations.
Peri od 1—Thetimeoverwhichthenoisevariation
makes a full c ycle. For example, a setting of 20
means one cycle per 20 frames.
Amplitude 1—The strength of the variation (in
percent).Thisoptionusesthesametypesofunits
as the Basic Torque spinner.
Phase 1—Offsets the variation pattern.
Peri od 2—Thenexttwospinnersprovidean
additional variation pattern to increase the noise.
Amplitude 2—Thestrengthofthevariationofthe
second wave in (percent). This option uses t he
same types of units as the Basic Torque spinner.
Phase 2—Offsets the variation pattern of the
second wave.
Par ticle Effect R a nge group
Lets you restrict the Motor effect’s range to a
specific spherical volume. This affects particles
systems only; it has no effect on dynamics.
Enable—When on, lim its the range of the effect to
a sphere, displayed as a tri-hooped sphere. The
effect falls off increasingly as the part icles near the
boundary of the sphere.
Range—Sp ecifies the radius of the range of the
effect, in units.
Display Icon group
Icon Size—Sets the size of the Motor icon. This is
for display purposes only, and does not alter the
Motor effect.

, spinning them through a
whirling vortex, a nd then moving them down a
long, thin spout or
vortex well . Vortex is useful for
creating black holes, whirlpools, tornadoes, and
other funnel-like objects.
The space warp sett ings let you control t he vortex
shape, the well characteristics, and rate and range
of particle capture. The shape of the vortex is also
affected by par ticle system settings, such as speed.
